I was speaking at a winter conference in Canada - and the word cold took on a whole new meaning to me. The temperature was minus-40 Fahrenheit - literally the coldest temperature I had ever experienced. When I walked in the room, people stood and sang, "Freeze a jolly good fellow." I really don't like to wear hats or hoods, but I learned to do it that weekend. One Canadian teenager told me he had been outside on his farm, in this cold, for 30 seconds and his ear literally froze - and part of it broke off. That is cold. I had about a five-minute walk ahead of me - believe me I had my parka hood on! I didn't realize you can do permanent damage in no time.
